TABLETVEOR use IN REMOVING HAIR.

SPECIFICATION forming part of Letters Patent N 0, 330,716. datedNovember 17, 1885.

Application filed June 24, 1885. Serial No. 169,690.

,To allwhom it may concern.-

Be it known that I, SAMUEL RIDewAY KENNEDY, of Philadelphia, in thecounty of Philadelphia,and in the State of Pennsylvania, have inventedcertain new and useful Improvements in Tablets for Use in Removing Hair;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,in which- Figure 1. shows a perspective View of the tablet, and Fig. 2 atransverse sectional view of the same.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to provide a new article of manufacture;and to this end my invention consists in the tablet composed of asubstance or compound for use in removing hair, covered with aprotective coating adapted to keep out moisture and air, substantiallyas hereinafter described, and more specifically pointed out in theclaims.

In the drawings, A designates the tablet, which consists of the mainportion B, covered by the film or coating 0.

I use the substance and compound described and covered by the claims inthe application No. 157,499 filed by me. Such substance and compound, asset forth in that application, consists of a sulphide of an alkalinebase, as sulphide of barium or sulphide of calcium, in conjunction ormixed with a starcl 1, resin, gum-mastic, or equivalent dilutants.

In order to keep this substance or composition for use in removing thehair, as described, inert and unchanged until it is desired for use, itis necessary to protect it from air, moisture, and oxidizing influences.In order to do this most completely while having the compound in themost convenient form for use, I make up the composition into tablets bycompression and then coat each tablet with an air and water proofcoating or film. Each tablet is of a size just sufficient for anordinary shavethat is, for the removal of the hair from the face. Whereonly enough .of the composition toremove the hair from a (No model.)

portion of the face is desired, of course the tablets can be madecorrespondingly smaller.

If, as has heretofore been done, it be attempted to keep thehair-removing substance in the quantity and not made up into tabletswith protective coating, as set forth herein, the substance willdeteriorate rapidly on account of the unavoidable access of air andmoisture when anyof the substance is taken for use.

As put up by me in tablets covered with the protective coating, asufiicient quantity of the composition can be taken at any time withoutdisturbing or exposing the rest of the material or composition.

The tablets can be stored away'or carried about without danger ofdeterioration, or of their injuring anything with which they come incontact.

The compound or substance may, as desired, be molded or pressed intocakes or tablets while moist or in the dry state. Even if the particlesshould not tend to cohere very strongly, the protective coating put onwould hold them together. I prefer to make this coating of somesoluble'substance which will make a film capable of resisting andkeeping out the air and moisture usually contained therein, and soinsuring the protection of the contents of the cake from oxidizinginfluences, but will be easily dissolved when the cake or tablet isplaced in water. I

l contemplate using for the coating some soluble varnish or parafifiineor wax; but do not intend to limit myself to any material therefor.

As most if not all the agents heretofore known or used for or inremoving the hair are materially affected and deteriorated by air andmoisture, it is obviously of very great advantage to put them up, as Icontemplate doing, in the form of coated tablets or cakes. 0

The composition which I prefer contains a sulphide 'of an alkalibasesuch as sulphide of barium, sulphideof'calcium, sulphide of iron, orsulphide of potashjas the active agent,

mixed with starch, resin, gum-mastic, or their 5 equivalents.

Of these suggested compounds I prefer the one consisting of sulphide ofbarium in conjunction with starch.

Having thus described my invention, what I claim is 5 l. A tabletcomposed of a quantity of sulphide of an alkaline base mixed withstarch, and covered with a protective coating, substantially as and forthe purpose described.

2. A tablet consisting of sulphide of barium 10 mixed With starch or,other dilutant and coated with a protective covering, substantially asand for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this19th day of June, A. D. 1885.
